13 This is a 64-bit timer found on TI's DaVinci architecture devices. The timer
14 can be configured as a general-purpose 64-bit timer, dual general-purpose
15 32-bit timers. When configured as dual 32-bit timers, each half can operate
16 in conjunction (chain mode) or independently (unchained mode) of each other.
17
18 The timer is a free running up-counter and can generate interrupts when the
19 counter reaches preset counter values.
